Problems solved by technology

The latter has too high technical requirements and is not suitable for users or even on-site service engineers to master; although the difficulty of the former has been reduced, there are still problems such as unintuitive logical topology and inflexible configuration.

Embodiment Construction

[0017] The following combined with the attachment and the specific embodiments further explains the present invention in detail.

[0018] The program control function of the SCADA system should at least meet the following needs:

[0019] ? Convenient and flexible configuration;

[0020] • Audit and friendly inspection;

[0021] • Efficient and reliable execution;

[0022] • Execute the status feedback accurately and timely.

[0023] The program control function of the SCADA system can be deconstructed into four modules: configuration, topology display, execution, and execution status.The data organization of the program control determines its configuration method, and the program control topology display, execution, and execution status display needs to be implemented by reading the program control configuration.Therefore, the data organization method provided by the SCADA system software is the foundation of the program control function and the core of the implementation of the p...

Abstract

The invention provides a structural-configuration-based multi-branch program control implementation method. The method comprises four parts, namely data organization, a configuration tool, a program control service and a monitoring tool. As an great improvement of the traditional multi-branch concurrent program control implementation mode, the method has the characteristics that variable and invariable parts of the functions are divided clearly based on multi-channel program control on the object; the variable part is configured by a user; the invariable part is realized by a program; and program reusability and configuration readability are greatly improved on the condition of not affecting high efficiency and flexibility of multi-branch program control. Based on the data organization characteristic of the object, the program control reality structure is modeled, the data organization method provided by the original system is compatible, the configuration mode that supervisory control and data acquisition (SCADA) system software has the consistent function is maintained, and the user can understand and master the method easily. By the simple and intuitive configuration mode, the configuration work load and the door threshold for the user to use the program control function are reduced, efficiency is improved, and maintenance cost is saved.

Description

Technical field [0001] The invention involves the implementation method of multi -road branch program control in the data surveillance and collection system (SCADA). Background technique [0002] Today, the degree of industrial automation is getting higher and higher, the basic single -point remote control function provided by traditional data monitoring and acquisition systems (SCADA) can no longer meet users' requirements for system efficiency and reliability.Program control (smooth control, sequence control) function is the expansion of basic remote control functions. Support users to organize multiple single -point remote controls according to actual needs.Improve the operation efficiency and reliability of the system. [0003] The traditional program control method only supports a set of single -point remote control operations in order of linear order, that is, multiple single -point remote control is arranged into a series of sequences connected by a team, and the single -p...
